Diplomatic and the Cid revisited: the seals and mandates of Alfonso VII

The royal chancery of the kingdom of León- Castile appears to have adopted the use of the seal towards the middle of the twelfth century. Examination of the surviving impressions from the reign of Alfonso VII (1126-57) suggests that he had at his disposal not one seal but two. They were sometimes used for the authentication of the solemn diplomas by which lands or privileges were granted; it is suggested that they were used also for sealing the short administrative orders called mandates. Documents of this latter sort, which have not hitherto been studied, appear to derive from the mandates used by Aragonese rulers of the early twelfth century, and they in their turn from the Capetian mandement and the Anglo-Norman writ. The use of sealed mandates in Alfonso VII's chancery is a further example of the play of foreign influences upon the kingdom of León-Castile at this period and may be of more than fugitive interest to historians of literature who are concerned to date the composition of Spain's most famous medieval epic, the Poema de Mio Cid.
